7.2. Add Additional Data Center
This lab shows you how to customize your standard Red Hat Enterprise Virtualization environment by adding an additional data center. This lab uses Red Hat Enterprise Linux hosts, but you can use Red Hat Enterprise Virtualization Hypervisor hosts instead, if you prefer. In this lab, you will learn how to create virtual machines in your new data center.
This lab assumes that you have successfully completed all the sections in the basic setup chapter. You should have correctly installed and configured Red Hat Enterprise Virtualization, and have configured shared storage and logical networks.
Lab 7 - Objectives
This lab takes you through the tasks necessary to install and set up Red Hat Enterprise Virtualization with multiple hosts and shared storage. You will also learn how to configure networks and how to add ISOs in order to create virtual machines. This lab should take you about 35 minutes.
Lab 7 - Requirements
Ensure that you have the following:
Red Hat Enterprise Linux Hosts
- Minimum - Dual Core server, 2 GB RAM and 10 GB Storage, 1 Gbps network interface
- Recommended - Dual socket server, 16 GB RAM and 50 GB storage, two 1 Gbps network interfaces.The breakdown of the server requirements is:
- For each host: AMD-V or Intel VT enabled, AMD64 or Intel 64 extensions, minimum 1 GB RAM, 3 GB free storage and 1 Gbps network interface.
- For virtual machines running on each host: minimum 1 GB RAM per virtual machine.
- For each host, a valid Red Hat Network subscription to the
rhel-x86_64-rhev-mgmt-agent-6channel.
Storage and Networking
- One or more of the supported storage types (NFS, iSCSI and FCP).
- One static IP per host which is resolvable by the DNS server.
- An NFS mount point for an ISO directory if you choose to configure an ISO share external to the Red Hat Enterprise Virtualization Manager Server.
Lab 7 - Configuration
The following figure and table list the environment parameters and object names which will be used consistently throughout this lab. It is strongly recommended that you use these entities in your evaluation environment to ensure the names are resolvable. You may alter them if necessary, but make sure you have an equivalent name for each component.
